Carole - I had a closer look and I really believe that the William Harman with his sons on the 1911 is your family. He remarried in 1913 to Hannah Rivett, and in 1911 she was living at 29 South Street, just 3 houses away from William at 35. The ages for William and Frederick match, as does the occupation of William. Sidney and Frank would not have been born yet and the missing Harry, Jane and William could be explained by William age 20 would probably be on his own. Jane and William ages 11 and 13 could have been sent to live with relatives or even sent away to school, as their mother died a couple of years previously. As William and the boys were only living in 1 room, there probably just wasn't enough room for everyone. What do you think?
